Indoor positioning system based on bluetooth low energy technology and a nature-inspired optimization algorithm
Primož Bencak, Darko Hercog, Tone Lerher, 2022, original scientific article

Abstract: Warehousing is one of the most important activities in the supply chain, enabling competitive advantage. Effective management of warehousing processes is, therefore, crucial for achieving minimal costs, maximum efficiency, and overall customer satisfaction. Warehouse Management Systems (WMS) are the first steps towards organizing these processes; however, due to the human factor involved, information on products, vehicles and workers may be missing, corrupt, or misleading. In this paper, a cost-effective Indoor Positioning System (IPS) based on Bluetooth Low Energy (BLE) technology is presented for use in Intralogistics that works automatically, and therefore minimizes the possibility of acquiring incorrect data. The proposed IPS solution is intended to be used for supervising order-picker movements, movement of packages between workstations, and tracking other mobile devices in a manually operated warehouse. Only data that are accurate, reliable and represent the actual state of the system, are useful for detailed material flow analysis and optimization in Intralogistics. Using the developed solution, IPS technology is leveraged to enhance the manually operated warehouse operational efficiency in Intralogistics. Due to the hardware independence, the developed software solution can be used with virtually any BLE supported beacons and receivers. The results of IPS testing in laboratory/office settings show that up to 98% of passings are detected successfully with time delays between approach and detection of less than 0.5 s.

Potentials and possibilities for a holistic-glamping site in Pomurska region of Slovenia : 1st Cycle Academic Bachelor's Studies Graduate Thesis
Sona Shaji, 2022, undergraduate thesis

Abstract: Glamping, camping the luxurious way of has the potential to provide a unique experience. Glamping is the best alternative for the people who want to have an outdoor experience but at the same time a comfortable stay. This study aimed to develop a marketing plan for a holistic-glamping site in Pomurska region of Slovenia. A structured questionnaire was used to survey (N=201) potential glampers and campers online. The results have indicated that tree houses and cabins are the most preferred type of accommodation facilities indicated by the respondents who also prefer to have their glamping sites in the mountains or near river streams. Luxury and closeness to the nature are always the main identified characteristics of glamping. But the accommodation facilities should contain luxury while also the same time minimal infrastructure as it should not damage the environment with a lot of infrastructures. In addition, the respondents preferred anti-stress treatments, contact with nature, new experience, and authenticity in the holistic glamping. Relaxation and adventure are the main motivations that motivate the people to do glamping in Pomurska. Because of its focus on understanding glamping from the perspective of potential customers, this paper contributes to broadening the conceptual understanding of glamping and provides a platform for further research.

Nature-inspired algorithms for hyperparameter optimization : magistrsko delo
Filip Glojnarić, 2019, master's thesis

Abstract: This master thesis is focusing on the utilization of nature-inspired algorithms for hyperparameter optimization, how they work and how to use them. We present some existing methods for hyperparameter optimization as well as propose a novel method that is based on six different nature-inspired algorithms: Firefly algorithm, Grey Wolf Optimizer, Particle Swarm Optimization, Genetic algorithm, Differential Evolution, and Hybrid Bat algorithm. We also show the optimization results (set of hyperparameters) for each algorithm and we present the plots of the accuracy for each combination and handpicked one. In discussion of the results, we provide the answers on our research questions as well as propose ideas for future work.
Keywords: artificial intelligence, artificial neural networks, machine learning, nature-inspired algorithms, evolutionary algorithms

Godinje settlement - adaptive reuse and revitalization
Jovana Dragović, 2019, master's thesis

Abstract: The Master’s thesis deals with the valorization and restoration of Godinje, the first village in Montenegro with the status of immovable cultural property. The project encompasses an analysis of the present state of the cultural heritage, research of traditional architectural elements of the crmnica house, as well as the role of man in space. An important factor in the development and preservation of architecture is the awareness of space and the factors that define it. With the aim of encouraging the proper maintenance of cultural heritage, while giving purpose to certain objects, the village planning has been resolved. By emphasizing the spatial principles and traditional techniques of construction, and thus the education thereof, the value is emphasized and further development of Godinje is made possible.
Keywords: Godinje, crmnica house, spatial principles, nature and man, culture, language of architecture, cultural heritage, valorization

Sociological survey of the current status and nature conservation in relation to the development of tourism in the cadastral of Tatranská Lomnica
Michaela Ližbetinová, 2014, review article

Abstract: The main part of the cadastral of Tatranská Lomnica belongs to the Tatra National Park. The activity of humans is limited there because nature is protected by law. This is the first time there will be building of new accommodation and sport facilities, especially after November 2004 when was severe wind damage in the Tatra region. In this thesis we focus on the opinions of respondents on the current state of the environment and its protection in the municipalities of the cadastral Tatranská Lomnica in relation to the present tourist business development.
Keywords: Slovakia, Tatra, national parks, nature protection, regional development, tourism

Relation between plant species diversity and landscape variables in Central-European dry grassland fragments and their successional derivates
Igor Paušič, Danijel Ivajnšič, Mitja Kaligarič, Nataša Pipenbaher, 2017, original scientific article

Abstract: A systematic field survey of an area of 843 ha in the traditional Central-European agricultural landscape of Goričko Nature Park in Slovenia revealed 80 fragments of dry semi-natural grasslands. Vascular plant species diversity was studied in relation to landscape variables and to threat (Slovenian red-listed species). Our results show that fragment size does not affect plant species diversity. In addition, fragment shape index is not related to Alpha diversity. Higher Alpha diversity was observed for abandoned grassland fragments. The lowest Alpha diversity was perceived on more mesic fragments, where habitat specialists are much scarcer. It was confirmed that the highest diversity of specialists are in the driest fragments, both still mowed and abandoned. With an increase in the number of distinctly different bordering habitat types, the total number of species per fragment generally does not increase, except in the case of those fragments that are already in different succession stages. Abandoned and typical dry grasslands are associated with a higher number of bordering habitats. Typical dry grassland fragments and abandoned ones, which probably derived mostly from drier (less productive) grasslands, are found on lower altitude and have a lower shape index. Habitat specialists Sedum sexangulare, Polygala vulgaris and Spiranthes spiralis have higher frequency in fragments with a lower shape index. This means that these oligotrophic specialists occur in smaller fragments. But Orchis morio has higher frequencies of occurrence on polygons with a higher shape index, which confirms the observation that this species occurs in larger and more irregular fragments, as well as close to houses and fields and along the roads.
Keywords: habitat specialists, traditional agricultural landscape, semi-natural dry grasslands, Goričko Nature Park, NE Slovenia

Tamara Višnić, Ljubica Ivanović Bibić, Smiljana Đukičin Vučković, Anđelija Ivkov-Džigurski, Eva Konečnik Kotnik, 2017, original scientific article

Abstract: This paper discusses the methodological procedures of application of teaching aids through the subjects: World around us, Nature and Society and Geography, as well as an adequate choice of teaching resources that encourage students to earn a permanent knowledge. The idea is to use teaching aids in active teaching and to turn it into the practical use of the material, in order to efficiently adopt the fundamental knowledge about the nature of science in the classroom teaching. The procedures are identified, which are especially important from the point of maximum achievements in teaching the use of teaching aids, and especially significant for subjects the World around us, Nature and Society and Geography. The aim of this study was to determine the importance of teaching aids in active teaching, as well as whether the student becomes mentally active participant in the educational process using teaching aids. The study involved class teachers (154) who evaluated the importance of teaching resources for permanent adoption of knowledge of students. In addition, the survey was analyzed and different types of learning resources in terms of their values in the activation of thinking in students were analyzed as well. This survey has confirmed the hypothesis about the importance of teaching aids for thoughtful activation of the students.

Back to nature: exploring the potential for implementing the Norwegian idea of outdoor days in the Slovenian school system
Katja Gomboc, 2016, other scientific articles

Abstract: Nowadays it is common to use the expressions ‘in the classroom’ and ‘out of the classroom’ (outdoors). In this article the word ‘outdoors’ will be replaced with the words ‘in the natural environment’, ‘into the natural environment’ and ‘within the natural environment’. These words accent the equal importance of nature as a learning area, a concept that is often forgotten, neglected or ignored. In this area, Norway has forged a real connection between people and nature, a way of life called “friluftsliv,” and has used experiential learning based on learning and playing in an outdoor area. In this article is presented a research study of teaching in nature, the Norwegian nature-oriented curriculum and the implementation of nature practice in the Slovenian school system.
Keywords: nature, teaching, teaching outside the classroom, free play
